CULTIVATOR William T. Smith, McDonoug h, Ga. Application September 16,1935, Serial Nb. 40,840

This invention relates to cultivators.

The objects of the present invention are to provide a cultivator whichcan be used to cultivate cotton, peas, corn, beans, or any small plantof like character without covering the plants with soil, and: thatdestroys grass that comes up with the plants, and which cultivator isadjustable laterally at. both ends.

"Further objects of the invention are to provide a cultivator of thecharacter referred to that is-strong, compact and durable, thoroughlyreliable for' its intended purpose, very simple to manipulate, andfthatis comparatively inexpensite to manufacture.

With 'therforegoing andother objects in view the invention consists ofanovel construction, combination and arrangement of parts, as will behereinaftermore specifically described'and illustrated in the.accompanying drawings, where'- in is' disclosed an embodiment of theinvention, but it is to be understood that changes, variations, andmodifications may be resorted to without departing from the spirit ofthe claims hereunto appended. .1

In the drawings wherein like reference characters denote correspondingparts throughout the several views V Figure. l is a side elevation of.the cultivator constructed in accordance withthe present invention, VFigure 2is a horizontalydetailed section taken substantially on theline' 2 -.2 of' Figure 1 and looking downwardly. e V

Figuregl'is'a vertical detailed section taken substantially 'on theplane of line 44 of Figure 1 and looking forwardly. v

Figure 5 is a horizontal section through one of the supporting-platestaken substantially on the plane of line 5-5 of Figure 1.

Figure 16 is 'a'p'erspe'ctive view of one of the cultivator blades.

Figure '7 is a perspective view of one of the supporting plates removedfrom the auxiliary beams.

Referring to the drawings in detail the numeral [0 indicates the centralhorizontally disposed beam which is formed of an elongated metal bardisposed in edgewise position. The forward end of the central beam isturned up at right angles to the plane of the beam to form theupstanding leg H. In the leg I! is a series of openings l2 in any one ofwhich may be attached the single- 3 Claims. (01. 97-170) treeby. whichthe cultivator is drawn. Near the rear end the central beam has a twistl3 forming a rear extension at right-angles to the plane of the beam. TI 1 Across an intermediate'po'rtion of the central beam 'lflis a'cross-head A. There is another cross-headB across the rear end of thebeam. The cross-head A is formed of two bars l5,"l6, the former beingabove and the latter being below the central beam Ill. The lower bar I6of the crosshead A is bent at the center into-a channel ll' whichoverlaps the lower portion of the central beam 1. The upper bar l5 hasthe lower face abutting the upper edge of the central beam l0 therebyclamping the intermediate portion of the' central'beambetwe'en the twobars.

The rear cross-head B is formed of a pair of aligned bars 1'8, [9, thecenters of which are secured by the bolt 20 to the extension 14. There Yis a pair of auxiliary beams 2|, 22;o'n'e on each side' of the central''beam l0. These auxiliary beams are of less length than the central beamI0 and are parallel iwiththe central beam and with each other. Theauxiliary beamsand thecentral beam lie in substantially the same horizontal plane. 'At each end, each of the auxiliary beams is twisted'as at23;24 to form terminals 25, 26 at each end which lie in a plane at rightangles 7 to the bodies of' the auxiliary beams. The extensions 26 onthe-iorward'ends of the auxiliary beams fit between the upper'and lowerbars I5; IS on the forward cross-head A and are bolted thereto by theboltsll. Theupper and lower bars I5, l6 of the forward cross-head Aadjacent each end are provided with two or more registering openings 28to receive the anchoring bolts 21 so that the auxiliary beams 2|, 22 maybe adjusted laterally with respect to the central beam. The rearextensions 25 on the auxiliary beams 2|, 22 fit between the upper andlower bars I8, I 9 of the 40 rear cross-head B andare'bolted thereto bythe bolts 29. Adjacent each end the upper and lower bars I8, are formed"with two or -more registering openings'3ll to receive the bolts 29 andthis construction provides for adjusting the rear ends 5 of theauxiliary beams laterally with respect to the central beam Ni. V v

The forward lower end of the handle posts 3|, 32 are bolted as at 33 tothe central beam Ill between the crossheads A and B. The handle posts 50incline outwardly and upwardly from the central beam and terminate inthe handles 34. The handle posts are provided with a U-shaped brace theupright legs 35, 36 of which are bolted as at 31, 38 to intermediateportions of the handle 55 posts. The bight or crown 39 of this U-shapedbrace is anchored to the upper face of the upper bar [8 of the rearcross-head B by the head of the bolt 20 which bolt clamps the upper andlower bars l8, I9 to the rear extension l4 on the central beam l0.

Near the twists 23 at the rear portions of the auxiliary beams 2|, 22are secured in edgewise relation the rectangular supporting plates 45,there being one supporting plate for each auxiliary beam. These plates40 depend from the auxiliary beams in vertical planes. Each of thesupporting plates 40 is formed in the same manner and.. referring toFigure '7 where one of them is shown, it is believed that a descriptionof one will teach the construction of the other. In the upper margineach supporting plate 40 is formed with a pair of openings 4| to receivethe pair of bolts 42 which anchor the upper ends of the plates to therespective auxiliary bars. In the opposed side margins each plate 40 isprovided with parallel slots 43. In the margin at the lower end eachsupporting plate 40 has a pair of bolt'holes 44.

To the leading side of each supporting plate 40 is attached an elongatedcultivating blade .45. The upper end of each cultivator blade is formedwith an elongated slot 46 and below'the slot and in alignment therewithis a bolt opening 41. The slot 46 registers with the slot 43 adjacentthe leading side of the supporting plate. The opening 41 registers withthe bolt openings 44 adjacent the leading side of the supporting plates.The lower portion 48 of each cultivating blade extends below the loweredge of the supporting plate and is pointed so as to easily penetratethe soil as the cultivator is drawn along in the process of cultivatingthe soil.

There is one fender or soil leveling blade secured to an intermediateportion of each of the supporting plates 40. Each of these fenders orleveling blades is formed with a straight shank 49 that fits flushagainst'the inside of the intermediate portions of the supporting plate40 and also an outwardly diverging free portion 50. The

' shanks 49 of the leveling blades are secured to the supporting platesby a pair ofhorizontally aligned bolts 5|. The shanks of these bolts 5|extend through the slots 43 in the supporting plates and the forwardbolts of the pair extend through the slots 46 in the cultivating bladeswhich construction permits vertical adjustment of the leveling blades.

Below the leveling blades 56 are the weed cutting and destroying blades,one being secured to each supporting plate. Each of the weed cuttingblades has a rear outwardly diverging portion 52 and a straight shank 53and this shank is secured to the outer face of the lower portion of thesupporting plates by means of a pair of horizontally aligned bolts 54.The shanks of the bolts 54 extend through the openings 44 in the bottomof the supporting plates and through openings in the straight shanks ofthe weed cutting blades;

The shank of the forward bolt 54 of the pair also extends through theopening 41 in the cultivating blade 45 which is secured to the inside ofthe supporting plate by this bolt. The lower or weed cutting blades arefixed to the supporting plates. The outwardly diverging parts 52 of theweed cutting blades are substantially longer than the diverging portionsof the leveling or fender blades. The outwardly diverging portions 56 ofthe leveling blades are disposed at the same angle with respect to thesupporting plates 40 as the outwardly diverging portions 52 of the weedoutting blades but are not in the same vertical plane because thestraight shanks of the leveling blades 2 are bolted to the inside of thesupporting plates while the straight shanks 53 of the weed cutting Whatis claimed is:
